DescriptionCVE.org

A command injection flaw in PCP's linux_sockets PMDA allows malicious shell metacharacters via the network.persocket.filter metric. This failed validation lets attackers execute arbitrary commands as the PMDA user when metrics refresh.

AnalysisAI

Local privilege-relevant command injection in Performance Co-Pilot's (PCP) linux_sockets PMDA lets an authenticated user inject shell metacharacters through the network.persocket.filter metric, causing arbitrary commands to run as the PMDA user each time metrics refresh. Reported by Red Hat, it affects the pcp packages shipped across Red Hat Enterprise Linux 6 through 10 and OpenShift Container Platform 4. …

Attack ChainAIDerived

Hypothetical attack flow derived from CVE metadata

Access
Obtain low-privilege local access
Delivery
Set network.persocket.filter with shell metacharacters
Exploit
PMDA metric refresh invokes shell
Execution
Execute arbitrary commands as PMDA user
Impact
Access or tamper with PMDA-accessible data

Vulnerability AssessmentAI

Exploitation Exploitation requires the linux_sockets PMDA to be installed and active in PCP, and the attacker must be able to set the network.persocket.filter metric value (local, low-privilege access per CVSS AV:L/PR:L). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The supplied CVSS 3.1 vector (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, base 7.8) frames this as a local, low-complexity, low-privilege issue with full confidentiality, integrity, and availability impact but no scope change - consistent with code execution confined to the PMDA user's context rather than a network-facing compromise. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario A local user with the low privileges needed to set PCP metric values assigns a network.persocket.filter value containing shell metacharacters (e.g. a value that appends a semicolon and a command). …
Remediation Apply the updated pcp packages from Red Hat once released for your RHEL major version (6 through 10) or OpenShift Container Platform 4 - no vendor-released fixed version is stated in the available data, so consult https://access.redhat.com/security/cve/CVE-2026-16524 and the Bugzilla tracker at https://bugzilla.redhat.com/show_bug.cgi?id=2506023 for the exact patched build and errata. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, conduct a rapid inventory of all systems running PCP to identify scope and criticality; determine whether affected deployments have exposed interfaces or contain sensitive data. …
